Chrysanthemum plant named ‘DLFBLAN1’

ABSTRACT

A new and distinct cultivar of Chrysanthemum plant named ‘DLFBLAN1’, characterized by its upright plant habit; vigorous growth habit; dark green-colored leaves; uniform and freely flowering habit; strong upright flowering stems with numerous inflorescences; anemone-type inflorescences with white-colored ray florets and yellow green-colored disc florets; excellent postproduction longevity; and relatively tolerant to low and high temperatures.

Botanical designation: Chrysanthemum X morifolium.

Cultivar denomination: ‘DLFBLAN1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum X morifolium,commercially grown as a cut flower and hereinafter referred to by thename ‘DLFBLAN1’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Maasdijk, The Netherlands. The objective ofthe breeding program is to create new freely-flowering cut Chrysanthemumplants with attractive inflorescences, strong flowering stems andexcellent postproduction longevity.

The new Chrysanthemum plant originated from a cross-pollination on Mar.17, 2011 of a proprietary selection of Chrysanthemum x morifoliumidentified as code number DB 33767 as the female, or seed, parent with aproprietary selection of Chrysanthemum x morifolium identified as codenumber DB 34154 as the male, or pollen, parent. The new Chrysanthemumplant was discovered and selected as a single flowering plant fromwithin the progeny of the stated cross-pollination in a controlledgreenhouse environment in Maasdijk, The Netherlands on May 25, 2012.

Asexual reproduction of the new Chrysanthemum plant by vegetativeterminal cuttings since May 25, 2012 has shown that the unique featuresof this new Chrysanthemum plant are stable and reproduced true to typein successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘DLFBLAN1’. These characteristics incombination distinguish ‘DLFBLAN1’ as a new and distinct Chrysanthemumplant:

-   -   1. Upright plant habit; vigorous growth habit.    -   2. Dark green-colored leaves.    -   3. Uniform and freely flowering habit.    -   4. Strong upright flowering stems with numerous inflorescences.    -   5. Anemone-type inflorescences with white-colored ray florets        and yellow green-colored disc florets.    -   6. Excellent postproduction longevity.    -   7. Relatively tolerant to low and high temperatures.

Plants of the new Chrysanthemum differ from plants of the female parentselection in the following characteristics:

-   -   1. Disc florets of plants of the new Chrysanthemum are more        green in color than disc florets of plants of the female parent        selection.    -   2. Ray floret apices of plants of the new Chrysanthemum are more        pointed than and not as rounded as ray floret apices of the        female parent selection.

Plants of the new Chrysanthemum differ from plants of the male parentselection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have anemone-type        inflorescences whereas plants of the male parent selection have        single-type inflorescences.    -   2. Disc florets of plants of the new Chrysanthemum are yellow        green in color whereas disc florets of plants of the male parent        selection are yellow in color.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Deliradost’, not patented. In side-by-sidecomparisons plants of the new Chrysanthemum differ primarily from plantsof ‘Deliradost’ in the following characteristics:

-   -   1. Disc florets of plants of the new Chrysanthemum are more        green in color than disc florets of plants of ‘Deliradost’.    -   2. Ray floret apices of plants of the new Chrysanthemum are more        pointed than and not as rounded as ray floret apices of        ‘Deliradost’.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘DLFCAPO1’, not patented. In side-by-sidecomparisons plants of the new Chrysanthemum differ primarily from plantsof ‘DLFCAPO1’ in disc floret color as disc florets of plants of the newChrysanthemum are more green in color than disc florets of plants of‘DLFCAPO1’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Chrysanthemum plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photographs may differ slightly from the color valuescited in the detailed botanical description which accurately describethe colors of the new Chrysanthemum plant.

The photograph on the first sheet comprises a side perspective view of atypical flowering stem of ‘DLFBLAN1’ grown as a spray-type.

The photograph on the second sheet comprises close-up views of the lower(top of the photographic sheet) and upper surfaces (bottom of thephotographic sheet) of typical inflorescences and leaves of ‘DLFBLAN1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the spring in ground beds in aglass-covered greenhouse in Maasdijk, The Netherlands and under culturalpractices typical of commercial cut Chrysanthemum production. Plantswere initially given long day/short night treatments followed by shortday/long night treatments to induce flower initiation and development.During the production of the plants, day temperatures ranged from 18° C.to 22° C., night temperatures ranged from 20° C. to 25° C. and lightlevels averaged 8 klux. Plants were grown as single-stem plants and wereten weeks old when the photographs and the description were taken. Inthe following description, color references are made to The RoyalHorticultural Society Colour Chart, 2015 Edition, except where generalterms of ordinary dictionary significance are used.
